Firth makes an impact on the world of science

COLIN FIRTH is a published science report author - research he commissioned last year (10) into the human brain has been completed.

Classics include Cary Grant and Katharine Hepburn in The Philadelphia Story.

The Oscar winner was invited to guest edit Radio 4's The Today Programme in December (10) and as part of the show, he asked scientists to scan politicians' brains to find any differences depending on their political leanings.

The research has now been completed and published in journal Current Biology and lists Firth as one of the report's co-authors.

New York University's Professor John Jost has hailed the work, saying, "It is a useful contribution because it builds on and extends previous work.

"It will probably be several years before we understand the full meaning of these results. In the meantime, the field of political neuroscience could do worse than having Colin Firth as a scientific ambassador."
